Doctors in July last year surgically implanted bionic eyes in a 30-year-old man, helping him fulfill his dream of being able to see his son, Chang Gung Memorial Hospital Retina Division Director Huang Yi-hsiu (黃奕修) said on Thursday.
Huang said the man, surnamed Tso (左), had retinitis pigmentosa, which often leads to tunnel vision, but rarely causes total blindness.
About 8,000 to 10,000 Taiwanese suffer from the condition and there is no cure, but cybernetic eye implants can alleviate the condition, Huang said.

A patient surnamed Kao (高), who also had retinal dystrophy, was in 2017 the first person in Taiwan to undergo a cybernetic eye implant, Huang said, adding that Kao’s vision was close to 0.05 diopters after rehabilitation.
The hospital’s research team said that 96 percent of people with bionic eyes can see shapes, such as squares, triangles or circles straight after their surgery, and more than 60 percent can see objects about 10m away from them.
While their vision is likely to be far from perfect, bionic eyes allow people to perform basic activities, such as using utensils and opening doors, which is a vast improvement, Huang said.
However, bionic eyes are expensive and cost up to NT$6 million (US$194,408), Huang said, adding that bionic eyes are even more expensive in Europe.
All seven implants conducted by the hospital have been clinical trials and the bionic eyes were donations from the Chang Gung group’s charity organization, the hospital said.
Medical teams from the US and Europe have come to observe the procedures, the hospital said, adding that it was last month presented with a certificate for being an outstanding center for bionic eye surgery.
Bionic eyes are made up of microcomputers, antennae and microchips, and restores vision to the patient by receiving wireless signals sent from a camera mounted on a pair of glasses, Huang said, adding that they are charged wirelessly.
The electronic components are minuscule and do not cause the patient discomfort, he added.
SPACE VETERAN: Kjell N. Lindgren, who helps lead NASA’s human spaceflight missions, has been on two expeditions on the ISS and has spent 311 days in space Taiwan-born US astronaut Kjell N. Lindgren is to visit Taiwan to promote technological partnerships through one of the programs organized by the US for its 250th national anniversary. Lindgren would be in Taiwan from Tuesday to Saturday next week as part of the US Bureau of Educational and Cultural Affairs’ US Speaker Program, organized to celebrate the 250th anniversary of the signing of the Declaration of Independence, the American Institute in Taiwan (AIT) said in a statement yesterday. Lindgren plans to engage with key leaders across the nation “to advance cutting-edge technological partnerships and inspire the next generation of scientists and engineers,”
The Chinese Nationalist Party (KMT) caucus yesterday said it opposes the introduction of migrant workers from India until a mechanism is in place to prevent workers from absconding. Minister of Labor Hung Sun-han (洪申翰) on Thursday told the Legislative Yuan that the first group of migrant workers from India could be introduced as early as this year, as part of a government program. The caucus’ opposition to the policy is based on the assessment that “the risk is too high,” KMT caucus secretary-general Lin Pei-hsiang (林沛祥) said. Taiwan has a serious and long-standing problem of migrant workers absconding from their contracts, indicating that
UNREASONABLE SURVEILLANCE: A camera targeted on an road by a neighbor captured a man’s habitual unsignaled turn into home, netting him dozens of tickets The Taichung High Administrative Court has canceled all 45 tickets given to a man for failing to use a turn signal while driving, as it considered long-term surveillance of his privacy more problematic than the traffic violations. The man, surnamed Tseng (曾), lives in Changhua County and was reported 45 times within a month for failing to signal while driving when he turned into the alley where his residence is. The reports were filed by his neighbor, who set up security cameras that constantly monitored not only the alley but also the door and yard of Tseng’s house. The surveillance occurred from July
TRADE-OFF: Beijing seeks to trade a bowl of tempura for a Chinese delicacy, an official said, while another said its promises were attempts to interfere in the polls The government must carefully consider the national security implications of building a bridge connecting Kinmen County and Xiamen, China, the Public Construction Commission (PCC) said yesterday. PCC Commissioner Derek Chen (陳金德), who is also a minister without portfolio, made the remarks in a meeting of the legislature’s Transportation Committee, after Democratic Progressive Party Legislator Hsu Fu-kuei (徐富癸) asked about China’s proposal of new infrastructure projects to further connect Kinmen and Lienchiang (Matsu) counties with Xiamen. China unveiled the bridge plan, along with nine other policies for Taiwan, on Sunday, the last day of Chinese Nationalist Party (KMT) Chairwoman Cheng Li-wun’s (鄭麗文) visit
